The totally new Ultegra FB provides excellent efficiency and strength because of the extremely durable HAGANE gear. The Coreprotect feature provides excellent water resistance without creating a heavy rotation feeling. There are three key areas in the Ultegra FB that require protection; the roller clutch, the body, and the line roller. The new Ultegra also features G Free Body technology which has been developed by Shimano to shift the reel's center of gravity closer to the rod. By moving the center of gravity closer to the anglers hand position, the G Free Body helps to reduce fatigue and enhance casting comfort. The stiff XT-7 body create the perfect protection and support for the HAGANE gear, X-Ship system, and shielded A-RB bearings to work to their maximum effect and efficiency. The all new Ultegra FB is an eye-catching reel which is engineered to be reliable and longlasting due to the incorporation of Shimano's HAGANE gear, Coreprotect, and G Free Body.

X-Ship is a combination of features that work together to create much greater efficiency. By positioning the pinion gear close to the centre line of the large diameter drive gear, more power is transferred from the handle to the rotor. The pinion gear is also supported by two Shimano A-RB roller bearings. This creates more stability.

The HAGANE Drive Gear is produced by Shimano’s cold forging technology, without the need for additional machining. This delivers a long lasting smoothness, strength, lightness and power at the very heart of the reel. Traditional die-cast, machined gears are less durable under heavy loads.

CoreProtect prevents water entering the body, from under the rotor at the front of the body, and also into the Roller Bearing unit.

XGT-7 is an improved version of the tried and trusted Shimano XT-7 composite material. Used on some of the newest mid-priced reels XGT-7 is lightweight and stiff.

Shimano S A-RB bearings are high corrosion resistant A-RB ball bearings with an extra shield for improved protection against sand, salt or dust. S A-RB bearings are used in salt water reels.

X Aero Wrap is a worm gear oscillation system with a specially designed pitch to create optimal oscillation speeds. This provides superb uniform line lay to reduce loss of energy during the cast. X Aero Wrap is considered one of the best line lay systems in the world. AR-C Spool is a patented spool design with an angled spool lip. This design enables the line to leave the spool with less friction and in smaller coils resulting in longer more accurate casts.

AR-C spools are proven to reduce backlash and wind knots when using braid. AR-C spools are now standard on almost all Shimano reels.
